I upgraded to the latest version of WordPress. When I went to install, it acted like this was a new blog and asked for login, etc. None of my old posts, comments or categories came over.
Looking in the database, I notice that there are both a "wp_posts" and "posts" table in the database. The blog seems to display only the posts in "posts" and not in "wp_posts".
I tried to import the posts from wp_posts, but they still don't display. I also updated the guid to match the path shown in the "posts" guid field -- the old posts still don't show.
Any advice from here?
